QUOTE: Originally posted by Jetrock HOn3 (HO scale, 3-foot gauge) might be to your taste as the trains are somewhere between HO and N in size--imagine a layout with HO-scale buildings and people, but with trains only slightly larger in size than N scale, and curves that can be as tight as an N scale layout too. Not a bad choice if you have limited space for an indoor layout. Narrow-gauge stuff always tends to be rarer and cost more than standard gauge, but as most narrow-gauge railroads had small rosters and not a lot of rolling stock, it all evens out.[/br]
